TRUSTEE, OF TOLEDO, OHIO AIRWAY ELBOW ATTACHMENT FOR HOSE EXTENSIONS Application filed June 6, 1928.

This invention relates to accessories and extensions in airway cleaning systems commonly known as vacuum cleaners and has to do with converting portable cleaners into stationary or semi-stationary form. The general purpose is to conveniently extend hose pipe connections from the suction handle of portable machines or from the suction handle extension of stationary machines, such as are shown, for example, in my Patent No. 1,588,271, dated August 14, 1925.

The more particular objects are to make convenient the closeting of portable devices, to render the closeted machine suitable stationary service, to make a convenient hose hanger ready to receive the closeted cleaner into working relation with the hose, to fasten such hose hanger to partitions or walls of dwellings, or to the swinging doors of the closets therein, and other objects as may appear in thespeoifications and claims.

In my Patent No. 1,681,624, dated August 21, 1928, entitled Air-way cleaning cabinet, I have disclosed a cabinet adapted to support a cleaner of the air-way type with its suction handle in upright position, whereby the same may be operatively connected to an extension hose or the like, and the present application, as to certain features of the invention, constitutes an improvement over the system disclosed in the aforesaid patent.

To these ends the invention consists of the construction, design, arrangement and com bination of the parts and features herein specified and illustrated in the accompanying drawing, in which:

Fig. 1 shows a front elevation ofthe hose hanger partly in section and suggesting movementsof an l. thereof in dotted lines.

Fig. 2 shows a section of one of the metal stampings, four of which similar stampings are used in constructing the double Lshown in Fig. 1. j

Fig. 3 shows an elevation taken at right angles to that of Fig. 1, but with the L members in other adjustments than there shown.

Fig. 4 shows an airway cleaner and an extension hose thereof when attached to a partition or the door of a closet in connection with the hose hanger.

Serial No. 283,278.

Fig. 5 is a front view of a suitable support on which to set or rest the rollers of the closeted cleaner when used in connection with my hanger.

Fig. 6 is a fragmentary view showing a modification in which the tool is attached directly to the L.

Similar characters of reference denote like and corresponding parts throughout the several views.

In the drawing, 1 denotes a part of an upright wall, partition or door, to which is secured the attachment bracket 2, with a base 3, having screw holes 4, 4. To a lower p0rtionof the door 1, a rest 5 may be attached by screws passing through the bores 6, 6, there of, which latter rest is designed to carry the entire weight of the cleaner with which my device is used.

The device properly comprises a pair of elbows or sections 7 and 7', which may preferably be constructed from similar stampings, being each a pair of L-shaped shells 8, 8, semicircular in cross section and having flanges 8 and 8 which may be spot-welded together in forming them. They are completed by assembling rings 9 and 10, rigidly secured to abutting ends of the Us, and the interconnecting flanges of these rings slide freely so as to permit the Us to have relative rotary motion. The bracket 2 is designed to grasp the outer flange of the ring 9, by a springing or yieldable hold, while allowing free rotation, yet the flange of the ring 10 is designed to slide more freely within the curved over flange of the ring 9.

The outer end of the L 7 has a flaring ring member 11 adapted to rotatably receive the end of a suction pipe 13 of a cleaning system; and the outer end of the L 7 has a nipple ring member 12 adapted to have slipped over it, the end 14 of the suction hose 15 of a cleaning system. These rings 11 and 12, assist in assembling the halves of the Us and are shown in section in Fig. 1.

In addition to the yieldable hold of the bracket 2 upon the ring 9, in its grasping end 2, the bracket is flexible throughout its length so that when the pipe 13 of the supported cleaner 16, is to be connected to the member 11, the supported Us with the connected hose 15 may be slightly bent or sprung upwards so as to slip over and operatively connect with the end of the pipe 13.

The utility of the device consists in connecting the end of the suction pipe with a suction hose and furnishing a swivel pipe connection and extension, for freely reaching in various directions. This utility is enhanced by the means for suspending the swivel pipe connection from an attachment to an upright partition, wall or door; for it is apparent that the cleaner 16 may be removed by separating 1t from the ring 11 for floor sweeping purposes, or the handle end may remain connected to the ring, and the elbow device may be disengaged from the bracket end 2 so that the end of the pipe 13 may carry with it the L member with its swivelling pipe joint and the hose pipe extension connecting therewith, to be used for cleaning purposes other than floor sweeping. It is to be understood that when the cleaner is connected as shown, for many convenient purposes it may be put into operation by turning the valve 20 of the cleaner to direct suction through its pipe handle portion 13, in the manner disclosed in my Patent No. 1,345,550, dated July 6, 1920, so as'to use any ordinary application tool as 17 on the hose 15, when the L joint member is not removed from the bracket 2. It is apparent, also, that the tool 17 may be attached directly to the elbow end 7 as shown in Fig. 6 as well as intermediately by the hose-pipe 15; and in any case, the attached portion yieldingly rotates in or on the end of the elbow to which it is attached so as to accommo'date itself to the demands of the operator.

It will be understood that one of the important results accomplished by my invention is the ready conversion of a normally portable suction cleaner, which includes a source of suction and a suction pipe or handle in operative communication therewith,into a semistationary machine to which extensions may be applied, and which may be conveniently used for the cleaning of walls, ceilings, draperies and the like. The means by which this conversion is accomplished is the flexible and resilient'bracket arm 2, which may be suitably secured to a relatively stationary member, such as a wall, door or the like. The flexible bracket arm carries with it a hollow connector or coupling, one end of which is designed to receive the open end of the suction handle. According to the embodiment of the invention as herein disclosed, the hollow connector is shown as composed of two rotatably connected elbow pipe sections 7, 7', but it will be apparent that so far as the broad aspects of the invention are concerned, the number of sections of which the hollow connector is composed may be varied without departing from'the spirit of the invention, and the term hollow connector as used in the accompanying claims is to be given a broad interpretation.
